Application filed December 6, 1912, Serial No. 735,195; Renewed Eebruary'S, 1915. Serial No. 6,822.

To all whom it may concern:

Be it known that I, Groaon B; KELLY, a

citizen of the United States, and resident of equi-distant indicia 15.

Jamaica Plain, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in C0mbined Piano-Players and T alking-Machines, of which the following is a specification.

The object of my invention is to provide a new and improved combined player piano and talking machine, which is simple in construction, reliable in action, and easily adjusted to maintain substantial synchronization of the talking machine record and the perforated music sheet of the player piano.

In the accompanying drawing 1 have shown the front elevation of the upper part of a player piano combined with a talking machine according to my present invention.

The tracker 1. the music roll 2, and the take-up roll 3, for the perforated music sheet 4: are mounted in the conventional manner between the side walls 5 of a chest 6 and the said rolls are rotated in the conventional manner by means of a motor 16, preferably an air motor of any approved construction, the motor per se forming no part of the presentinvention. The speed of the motor is controlled by a tempo lever 7 in any well known manner.

The rotating support 8 for a talkin machine disk or record 9 is mounted'on the the record 9 on the support 8 and this disk 14 is provided on its rim with a number of There may be only one of such indiciarepresenting a full rotation of'the disk 1 or theremay be two of such indicia indicating half rotations or four indicia indicating quarter rotations,

and so forth as may be desired. These subdivisions or indicators are each marked 1, 2, 3, etc., respectively, so that these indicia can readily beafoilowed by the eye as the disk lei rotates. A pointer 17 projects from the right hand Wail 5 of the chesto over the rim of the disk 14 so that as the disk rotates the indicia 15 pass. said pointer. The music sheet 4: is provided along one edge, in this case,'the right hand edge, with a series of equally spaced indicia which are marked to correspond with the indicia on the rim of the disk 1%. For-example, if the rim of the disk 14- is divided into four parts the indicia 22} on the sheet are marked 1, 2, 3, 4, then the next indicia 1, Q, 3, at, and so on. Each subdivision or one of said indicia thus produced on the music sheet corresponds to one subdivision on the disk 14. In making the music sheet master one such mark a: of the music sheet is produced regularly on the moving master sheet for each fraction of a Complete rotation of the record disk 9. If the/disk 1+1 has but a single mark on its rim the indicia a on the edge of the music sheet will be separated from each other a distance corresponding to one full rotation of the disk 14, or which is the same, one complete rotation of the record disk 9. A pointer 18 projects from the right hand side wall 5 of the chest to the right hand edge of the music sheet or may slightly overlap the same. The speed of rotation of the record disk 9 is uniform throughout, as in all talking machines, and if thespeed of the music sheet is so adjus ted that its sub-division marks or indicia a appear at the pointer or marker 18 at the sameinstant that the corresponding sub-division indicia on the disk 14: appear at the pointer 17 the disk and the music sheet will be synchronized. If it should appear that the music sheet moves too slowly or too rapidly to obtain exact synchronizing it is only necessary to manually move the tempo lever 7 correspondingly to one side or the other sufliciently to slightly increase or decrease the speed of the motor and thereby the speed of the music sheet, so as to cause the corresponding indicia on the disk 14 and iusie sheet to register with their respective pointers at preciselv the same time.

Having described my invention what I claim as new and desire to secure byLetters Patent is 1. The combination With a player piano comprising a motor for moving a perforated music sheet, a manual means for controlling the speed of said motor and'a talking ma chine comprising a movable support, a motor therefor independent of the sheet moving motor, of a movable element driven by the record moving motor at a speed proportionate to-the speed of the record support and provided with permanent visible indicia, a pointer adjacent to said movable element, a perforated music sheet'driven by said sheet moving motor and provided with indicia, separated a distance to be traversed by the music sheet during one rotation of the record disk support and a fixed pointer adjacent to said sheet, the indicia on the movable element being so positioned and so driven that a mark comes opposite the adjacent pointer for each rotation of the rec-j 0rd support, whereby an observation of the two pointers and of the arrival of the indiciaon the element driven from the talking machine motor and on the music sheet, at said pointers, indicates any existing varia-. tion in relation to the speed of the driven elements and permits of rectifying such variation by means of themanual speed control for the music sheet motor, substantially as set forth. a

2. The combination with a player piano comprising a chest, a perforated music sheet onone of said rolls, music rolls in said chest and a motor for moving the perforated music sheet connected with said rolls and. a talking machine comprising a motor for rotating a record independent of the sheet moving motor, a disk mounted Within said chest and driven from the talking machine record motor at a speed proportionate to the speed of the record, indicia on the rim of said disk, said music sheet having indicia permanently produced thereon, said indicia being spaced at a length of the music sheet, which is to be trav rsed by the sheet during one rotation of the record support, in order to obtain 'synchronism. and fixed pointers extending to the said disk and to the said music sheet, the indicia on the movable elements being so positioned and driven that a mark comes opposite the adjacent pointer for each rotation of the sup-' port, when the disk and sheet aremoving synchronously, substantially as set forth.

3. The combination With a player piano comprising a chest, music rolls in said chest,

a perforated music sheet on one of said rolls, r i

a motor for moving said perforated music sheet, connected. with said rolls and a talk ing machine comprising a motor for rotat ing a talking machine record support independent of'the perforated sheet moving motor, a movable element driven from the talking machine record motor a speed proportionate to the speed of the record support, said element being located within said chest, equally spaced indicia on said element driven from the talking machine record motor,indicia permanently produced on the perforated music sheet, said indicia on the perforated music sheet being spaced at a length of'the music sheet which is to be traveled by 'said'sheet duringa predetermined part of a rotation of are record sup-' New York and State of New York this 1st day of December A.
